The Advanced Host Controller Interface (AHCI) is a paramount feature for ensuring that Windows will support all of the features that come with running an SSD on your computer, especially the TRIM feature, which allows Windows to help the SSD perform its routine garbage collection. The term “garbage collection” is used to describe the phenomenon that occurs when a drive gets rid of information that is no longer considered to be in use.
To enable AHCI, you’ll have to enter the BIOS of your computer and enable it somewhere within its settings.
TRIM is vital to extending the lifespan of your SSD, namely by keeping it clean under the hood. Windows 10 should enable this by default, but it’s worth double-checking that it has been enabled.
To make sure TRIM is enabled, open your command prompt and enter the following:
fsutil behavior set disabledeletenotify 0
A good part of your SSD speed is consumed in indexing files for Windows search. This could be useful if you store everything you have on your SSD, but you might be annoyed by it if you experience slow-downs due to the periodic indexing process that occurs every time you add new data to the drive.
